Lake Wahtopanah, also known as Rivers Reservoir, is a reservoir on the Little Saskatchewan River near the town of Rivers, Manitoba. Its dam is the Rivers Dam.[1]

The reservoir is about Script error: No such module "convert". wide and Script error: No such module "convert". long. Its deepest point is about Script error: No such module "convert".. Riparian flows are regulated by a Script error: No such module "convert". square gated conduit. High flows pass over a Script error: No such module "convert". wide concrete chute spillway. The reservoir stores about Script error: No such module "convert". and covers an area of about Script error: No such module "convert"..[3]
The drainage area is about Script error: No such module "convert". and extends well into Riding Mountain National Park.[3]
Rivers Dam supplements water supplies for irrigation, as well as providing the water supply for the town of Rivers, stock watering, and recreation (such as fishing and canoeing).[3]
The most popular species caught in the lake are northern pike, walleye, and yellow perch.[4]
History
The dam was built by the Prairie Farm Rehabilitation Administration in 1960 to supplement water supplies for irrigation.[3]
2020 flood
In late June and early July 2020, heavy rainfall caused a runoff event with record flooding on the Little Saskatchewan River.[3]
The flow peaked at about 300 cubic metres per second (10,600 cubic feet per second). The area received over Script error: No such module "convert". of rain over a 5-day period causing the lake to flood to the never-before-seen level of Script error: No such module "convert". above sea level, Script error: No such module "convert". above the full supply level.Script error: No such module "Unsubst".
The water level at the Rivers Dam reached record-high levels during the rainfall, affecting nearby communities including Brandon, Riverdale, and Whitehead. This caused the Manitoba government to lose confidence in the dam and to warn everyone down stream of the likelihood of dam failure and catastrophic flooding.[3]
Nearby municipalities declared states of emergency, and the city of Brandon put over 2,000 residents on evacuation notice.Script error: No such module "Unsubst". Approximately 83 people had to evacuate from their homes in the Rivers Dam flood zone area.[3]
Once the flood waters receded, the province was able to assess the dam, with interim repairs to the spillway being completed in February 2021. In July 2023, the Manitoba government announced that permanent rehabilitation work of the dam has begun.[3]
